Abstract
The invention provides a tool for turning external threads with big lead angles, which comprises a tool bar and a tool bit arranged in the tool bar and also comprises a tool bar sleeve. The tool bar is arranged in the tool bar sleeve; the diameter of the front end of the tool bar is longer than that of the rear end of the tool bar; the rear end of the tool bar extends into the tool bar sleeve; the front end of the tool bar is positioned on the end surface of the tool bar sleeve; a tool pressing screw is arranged at the front end of the tool bar; and the rear end of the tool bit extends into the tool bar and is fixedly connected with the tool bar through the tool pressing screw. The tool provided by the invention has the beneficial effects that the structure is simple, the operation is convenient, not only a screw with external threads with big lead angles can be machined, but also the angle of the tool bar can be adjusted at any time to meet the machining requirements on different screws with different lead angles, and the adjusting range of the angle is from 0 degree to 75 degrees.
Description
Technical field
The present invention relates to a kind of turning external screw thread and use cutter, relate in particular to a kind of turning major thread lift angle external screw thread and use cutter.
Background technology
The lead angle of conventional screw screw thread is below 10 °, and the whole scope of the adjustable angle of screw flight process tool is about 10 °, and the angle that when the different screw thread of processing, only need adjust cutter can satisfy the processing of common screw screw thread.But the lead angle of some screw flight reaches 53.6 °, considerably beyond the lead angle of conventional screw thread, uses the regular screw threads cutter can't satisfy the requirement of king bolt lift angle screw rod.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure and the big turning king bolt lift angle external screw thread of cutting-tool angle adjusting range to use cutter.
The present invention realizes through following measure: turning king bolt lift angle external screw thread is used cutter; Comprise knife bar and the cutter head that is arranged in the said knife bar, wherein, also comprise the knife bar cover; The point diameter of said knife bar is greater than the diameter of said knife bar rear end; The rear end of said knife bar is stretched in the said knife bar cover, and the front end retaining of said knife bar is on the end face of said knife bar cover, and the front end of said knife bar is provided with the push type broach screw rod; Said cutter head rear end is stretched in the said knife bar, and is fixedly connected with said knife bar through said push type broach screw rod.
Concrete characteristics of the present invention also have, and axially are provided with the rectangular slit of a perforation on the sidewall of said knife bar cover.
Be provided with the rectangular cylindricality cutter groove of a side opening of axial perforation in the said knife bar, said cutter head is arranged in the said cutter groove.
Beneficial effect of the present invention is: simple in structure, easy to use, not only can process the externally threaded screw rod of king bolt lift angle, and knife bar can adjust the processing request that angle satisfies different lead angle screw rods at any time, and the adjustment angle is at 0-75 °.The knife bar rear end is stretched in the knife bar; And be fixed together through push type broach screw rod and knife bar, the knife bar rear end is stretched in the knife bar cover, and the knife bar cover is fixed on the cutter platform; Adjusting behind the cutting face, centre-height of cutter head the knife bar cover compressed makes knife bar become as a whole with the knife bar cover; Be machinable left-hand thread or right-hand thread, when needs are adjusted the cutting face of cutter head, only need the angle of choosing dress knife bar to get final product; Wherein, the sidewall of knife bar cover is provided with the slit, is convenient to compress the knife bar in the knife bar cover; The sidewall of knife bar is provided with opening, conveniently cutter head is put into knife bar; The overall diameter of knife bar front end makes the knife bar cover prop up knife bar greater than the interior diameter of knife bar cover, guarantees that knife bar is firm when turning.
